Question

I have a dom table

select * from dom

dom table details:

id    name     skills
1     do         


        

Answer 1

Skills column looks like something you might want to map with many-to-many relationship with your original "dom" table. For example:

SKILLS      DOM         DOM_SKILLS
id | name   id | name   id_dom | id_skill
---'-----   ---'-----   -------'---------
 1 | C       1 | dom        1  |  1 
 2 | C++                    1  |  2

This way, your query might look bit more complex...

SELECT d.name, s.name 
FROM dom d 
JOIN dom_skills ds ON (d.id = ds.id_dom) 
JOIN skills s ON (ds.id_skill = s.id)
WHERE s.name LIKE '%C%' OR s.name LIKE '%C++'

...but your schema will be easier to manage (think about duplicate entries, updating etc.. the normal form stuff, which is at the moment violated by your schema).
